To those opening the store 👋 This extension allows you to draw boxes on the screen using only keyboard shortcuts. We have summarized the key points for each heading below. 【📋 Quick Reference】 ・✏️ Drawing a marker: Hold down the modifier key and drag → A rectangular marker appears on the screen. ・🧹 Clearing markers: Clear by tapping the set modifier key within about 0.5 seconds. ・🆓 Free Version: 1 setting tab, 1 simultaneous marker, drawing appearance is default style (key can be changed). ・⭐ Pro Version: 3 setting tabs, multiple simultaneous drawings, your custom style is reflected in the drawing, export/import of settings. ・⚙️ Settings: From the pop-up menu of the extension icon. Help and language switching are available from the companion page. ・⚠️ Caution: May not work depending on the site or display method. For sensitive screens, follow internal company rules. 【✨ What this extension can do】 ・🖥️ Screen Marker is a Chrome extension that allows you to draw rectangular markers on a web page you are viewing simply by dragging the mouse while holding down a modifier key. ・It is displayed directly overlaid on the browser's view area. 💼 Examples of uses: ・📸 Temporarily marking areas before taking a screenshot ・💬 Indicating areas you want to show during online meetings or classes ・🎬 Circling the area you want someone to look at during an operation demo 💡 Other points: ・The drawn markers remain on the page and will persist until the page is reloaded. ・There is a minimum drag requirement to prevent accidental drawing of rectangles from very small movements. ・You can manage settings such as color, key, and behavior from the extension icon's pop-up. ・Help and upgrade information can be viewed from a page within the same extension package. ・By default, markers are tied to the display of "that tab." If you switch between multiple tabs, it's recommended to establish a workflow, such as taking a screenshot or making a note before closing a tab, for peace of mind. 【🖱️ Basic Usage】 ✏️ Drawing: ・Hold down all modifier keys set in the popup and drag. ・The default is something like holding down both the left Shift and left Ctrl keys (can be changed in the product settings). 🧹 Keys and Clearing: ・You can assign different modifier key combinations for each setting, allowing you to use them for different purposes. ・To clear all drawn markers at once, press and release the assigned modifier keys within about 0.5 seconds. ⚠️ Notes: ・Depending on your keyboard or OS, some modifier keys, including left/right distinction, may not be detected as expected. ・We recommend testing in your own environment to ensure they do not conflict with other shortcuts before making them permanent. 🆓 Free Version vs ⭐ Pro Version: ・Free Version: Primarily supports markers associated with Setting 1. ・Pro Version: Can handle markers tied to multiple settings. ・If you want to keep markers visible for a long time, you can adjust the fade-out time and automatic fading behavior in the style settings. 【🎨 Marker Appearance and Style】 🛠️ Example adjustable items: ・Fill color・Opacity ・Border color・Opacity・Thickness ・Corner radius ・Line type (solid, double line, wavy, dashed, etc.) ⏱️ Other options: ・Fade out (fades after a set time) ・Display drawing indicator ・Follow scrolling or not ・Activate only on specific URL patterns ✨ Styling Tips: ・For high visibility: Yellowish fill and a dark border. ・For subtle explanations: Pastel tones with increased opacity. ・For color blindness or projection environments: Try combinations of high-contrast line colors and appropriately opaque fills. 🆓⭐ Differences between Free and Pro version (Style): ・Free version: You can change and save styles in the UI, but the default style will be used for actual drawing (Note that the preview and actual drawing might not match). ・Pro version: The saved style is directly reflected in the drawing. ・Even in the free version, you can change key assignments and flexibly set the key combination used for drawing. 【⚙️ Settings Tab and Key Assignment】 ・Pro Version: Three settings tabs (1, 2, and 3). Each can be assigned a different modifier key and style. ・Free Version: Only Setting 1. 🎭 Example Role Division (Pro): ・Setting 1: Highlighting important points ・Setting 2: Thin frame for supplementary explanations ・Setting 3: For temporary pointing 📚 Simultaneous Drawing: ・Pro Version: Can leave multiple markers on the screen simultaneously. ・Free Version: Only one at a time. You cannot add a new rectangle while a marker already exists. This leads to a flow of clearing between sections or considering Pro. ・It is recommended to follow the instructions within the product for default key assignments, and if there are conflicts, assign one of them to a different modifier key. 【💎 Free vs. Pro Differences】 🆓 Free Version: ・Basic screen marker functionality available without payment. ⭐ Pro Version: ・Through subscriptions via Stripe or lifetime purchases.

Product Changes: ・The boundary between the free version and the Pro version may change with updates. Please check the latest product description for details. 💬 Bugs/Requests: ・If there is a designated contact method, using that channel may result in a faster response than through reviews. 【💡 Introduction and Usage Tips】 🚀 Upon initial setup: ・Test on representative sites such as internal portals, learning management systems, video sites, and document tools. ・Confirm that the assigned keys do not conflict with existing browser shortcuts. 📦 Deployment: ・When distributing to multiple devices in educational institutions or companies, it is effective to use the exported settings as a template or to document the recommended keys. ♿ Accessibility: ・By utilizing Pro's styles to distinguish not only by color but also by line thickness, double lines, or dashed lines, the information is easier to convey even in projection environments. 📋 Logs: ・Enabling logs makes it easier to convey the situation when investigating bugs, but please handle them with care as they may include URLs and screen information. 🔄 Updates: ・When upgrading versions, checking the release notes or in-product announcements for behavioral changes or new options makes it easier to update manuals. 🔧 Coexistence with other tools: ・If used with another screen annotation tool, be careful of overlapping shortcuts or overlays, and it is easier to stabilize operation by assigning roles to one tool. 【🖥️ Interaction with the Screen】 ・The marker is drawn overlaid on the visible area of the tab you are viewing. The main target is the webpage area below the address bar, and it will not overlap the browser's UI itself. ・When scrolling the page vertically, if "Scroll Following" is turned off, the marker will remain at the drawn position. If it is on, the display will follow the scroll. ・In multi-monitor environments, the interpretation of coordinates and scale may change after moving the window to a different display. If the position looks unnatural, please clear the marker and redraw it. ・When used with split view or picture-in-picture, the appearance can change depending on which frame is "the tab." For streaming or recording, please check that there is no discrepancy between the viewer's screen and your screen. ・On special pages where the display is contained only within an iframe of the same origin, whether the overlay appears on the parent page or the child frame depends on the page structure. If it is not as expected, refreshing by opening the page in full screen or a separate tab may improve the appearance. 【🤝 Guide to choosing between Free and Pro】 ・For short demos or personal use, the free version is often sufficient if one highlight style is enough. ・If you want to distinguish between "Important," "Supplementary," and "Temporary Pointer" in a presentation using different colors or line styles, or if you want to highlight multiple areas simultaneously, the Pro version's multiple settings and simultaneous drawing are recommended. ・If your team wants to standardize colors or key bindings, using the export and import features in the Pro version settings makes management easier. 【📝 Summary】 ・Screen Marker is a Chrome extension that allows you to draw markers on the screen using modifier keys and dragging. ・It is helpful for situations where you want to draw attention to something on the screen, such as during presentations, education, demos, internal explanations, or reviews. 📌 Version Comparison: ・Free Version: Basic features and key assignment customization. ・Pro Version: Multiple settings, simultaneous drawing, full style reflection, setting migration, and more. 👣 Recommended Getting Started: ・A natural flow is to first test the basic functionality with the free version and then consider Pro when team use or visual consistency becomes necessary. 🔧 Troubleshooting: ・If the behavior changes after a Chrome or OS update, please try by reloading the extension or rechecking your key assignments.
